Missfire! Help Please!

[victor71]

My skyline yesterday decided to spaz out and start to miss fire around the 5k-7k rpm range. I just had new plugs put in so i dont think that is the the problem. can anyone help me out. i the car is a 94 model and its just done 100000kms. could it be old fuel injectors or what could be the issue here. please help me!!

coilpacks?

[Nic_A31]

In the stickies, mistifre under boost from 5000rpm

Cracked coilpacks, unless its something else for you?

What boost you running.........could be plug gap>>reset to 0.8mm and try again maybe

[victor71]

when i run 10psi its alrite but when i pump it up to 11.8psi it starts to missfire. this might sound stupid but how do you get the gap from 1.1 to 0.8?

Google is your friend too, seriously now

Type in google " how to gap spark plugs " & click on the first link.

[jinns]

Hey my car misfires alot, when i pull the engine to the max it seriously misfires, and when I try overtaking cars in the highway it doesn't stop misfiring, sometimes the boost starts pumping up and the rpm starts dropping no matter what I do till the car slows down, I have stock headers, turbo, trubo dump pipe, down pipe and suddenly a 3 inch exhaust pipe.

I changed my fuel pump, my plugs, my airflow meter which helped for a coupe of days but then it started again.

Help!!! when I start the a/c my engine starts stalling, and at idle my engine starts to dying out especially with a/c.

I broke my hoses that carry oil from above the engine where do i get the newer one?

Waiting for reply,

Falah

Fly me out to Hilton Riyadh Hotel for a couple of weeks & I'll bring you hoses and coilpacks.

All new; obtained from www.justjap.com

I'll have the last week of December + 1st week of January to fit the trip in.

if ur car is boosted, u should to regap the plugs to around .8 due to the change in turbulence in the combustion chamber. if it still misfires you have a bad coil

if car is not boosted, change ur plugs, if it still misfires u have a bad coil

if still mises you could have bad wiring to coil or bad wiring, or bad fuel mixtures, VERY VERY RARE

Faulty air flow meter can seem like a misfire if not experienced
